smart device database problem

hi all,
i want to connect the mfc smart device to odbc database but i found that smart device does not have such function to connect when setting up the environment, and i just type those code using crecordset and cdatabase class function and it didn't work, can anybody tell me what should i do?
thanks!

Can you create a DSN in the device's OS?
[I have previously posted code on how to programmatically add a DSN.]

Please post you current code to connect to the DB, otherwise we are guessing at what could be going wrong.
